摘要
本文从轨道方面就发展25t轴重货车的可行性,从轨道准静态效应、轨道垂向动力效应及轨道振动效应等方面对高质量低刚度的轨道结构进行了较全面的分析。分析认为,提高轴重是扩能的需要,运用现代科学技术和国内外铁路的运营经验,实现重轴重大型货车的低轮轨力和低振动效应的车辆和轨道的相互作用,是能够获得所期望的效果的。
The feasibility of adopting 25t axle load freight cars is discussed from the aspects of quasi-static effect, vertical dynamic effect, and vibration influence of track. The heavy mass and low stiffness track structure is proposed. It is shown that low wheel/rail interaction and low vibration in case of heavy axle loads could be obtained by using modern railway operating experiences and advanced techniques.
